Django Staticfiles

Django staticfiles is the most common problem you need to solve before putting your app on the production. In this tutorial, I and you will walk through the solution options, included.

• runserver: Only in development environment.
• gunicorn: Use gunicorn as your app server.
• nginx: Put nginx web server in a front of your app server (gunicorn).
• whitenoise: Let your django app self-serve static files.
